ELECTRIC MOTOR.

SPECIFICATION forming part of Letters Patent No. 264,848, dated September 26, 1882.

Application led February 3, 1882.

. To all whom at may concern Be it known that I, JOHN BATLEY, of the city and county of Philadelphia, and State of Pennsylvania, have invented an Improvement in Electric Motors, ot which the following` is a specification.

'lhe object of my invention is to construct an electro-magnetic motor wherein the direct lattraction of the electro-magnets to the armatures is utilized (at a longer range than commonly) to multiply by induction the initial potential of the current and to make an engine of any desired horsepower, said power being adapted to be increased or diminished without altering the speed ot' the working parts, the mechanism ot which is fully set forth in the followingspecilication and shown in the accom panyingdrawings,which form part thereof.

In the drawings, Figure lis a side elevation ot' my improved motor with a small por tion of the frame broken away. Fig. 2 is a plan ot1 same with a portion of the frame broken away. Fig. 3 is a sectional planthrough the magnets and armature. Fig. 4 is a front elevation ot' same detached from the machine; and Fig. 5 is an enlarged view of the starter, cut-olf, and connection with the battery elements, (detached from the machine.)

A is the frame, and carries axle B, upon which is secured iiy-wheel F, ratchet-wheel or its equivalent, D, and commutator E, which is electrically connected with the insulated stud E2 on the axle B; or the axle itself maybe properly insulated and take the place ot' said stud.

Eneircling the wheel D are rings or frames G, which are secured fast to frame A, and really form part of same.

The electro-magnets I are supported and secured to the frame G and operate armatures S, secured to levers J, pivoted at)l to extensions g from. the frame of the machine, and provided at the tops with pawls L, adapted to engage with the teeth of the ratchet-wheel D, with which they are kept in contact by springs Z. These levers J extend below the pivots j, as shown at J', and the bottom of the extension of one lever is pivoted at k with a leverbar K, which is pivoted to the next lever at an equal distance above the pivot j, to the end that when one lever is drawn forward by its- (No model.)

magnet the other is moved back an equal distance. There may be any number of electromagnets I and levers J arranged around the ratchet-wheel D; but I have only shown two, as myinvention comprehends two or more; and, if desired, one or more ratchet-wheels D may be secured to the shaft B. These magnets are made with a ceutralcore, i', and concentric tnbular rings t' t', the spaces between which and upon the outer rings are coiled with insulated wire, said coils being connected together in succession, one helix after another. These cores are joined together by a bar, I2, in the usual manner. It desired, any other form of electro-magnet may be employed.

The armatures S are made oblong, as shown in Fig. 4,-so as to take in part of allot' the corest' and 1"; and to give greater power and a longer throw to the armatures helices I' are made to encircle them, as shown, said helices being in circuit with magnets I, and to which they are secured.

The comtnutator E is provided with contactpieces e ofsuicient length to give the required stroke tolevers j, which is equal to one-halt' the pitch ot' the teeth of ratchet-wheel D, and the brushes M are made oi' springs secured to and insulatedt from the frame G, and press upon the commutator, so that one brush of a pair Vof magnets, as shown, makes contact before the other breaks contact, whereby the current is never broken, and the battery-circuit is always closed. rIhe brushes are connected with the magnets I I', and are jointly connected to a pin, It, which is in circuit by a wire with the negative pole ot the battery or current-gener ator. The stud E2 is connected through spring H with the positive poleoi' the battery.

To put on instantly (and thereby start the motor) one or more currents from batteries I use the following device: An upright, N, is secured to frame A, and carries with it contact-pieces s s', Sto., r r', &c., the pieces s s', &c., being connected with one pole of a corresponding number otl distinct elements, and pieces r r', tbc., with the other pole ot' said elements. In iront ot' these pieces a rod or insulator-plate, O, is adapted to reciprocate by means ot' a lever, P, which may be set by a lever, P', with notchesp in which a pin, p', on lever P enga-ges. To put on one or more ele- IOO ments, are plates Nl and O having respectively contactsurfaces a n', 85e., and o o', Ste.

v The surfaces a and o are doublethe width otl u and 0, and every additional element used requires an additional width of contact, as shown in Fig. 5, in which four elements are arranged to be placed in circuit with the machine. The plates N and 0 are respectively connected with stud R and spring H. 1n the position shown in Fig. l battery X is on the machine. Now, by pressing down the slide O the required distance (the next notch P) the contact-pieces r o' and s a will'come in circuit and put battery X also to the machine. Any number of elements or batteries may be used by following the construction shown in Fig. 5, in which t'our elements are used. The electro-magnets I I are arranged about the ratchet-wheel l), so that while one of the armatures is attracted and pulls the wheel the other is withdrawn, so that a series ot' continuous impulses is the result.

The voperation is as follows: The current from one poleot the battery or batteries passes down spring II. through stud E2 to commutator E, thence throughbrushes M alternately to one pole ot' the magnets I I', the other pole being connected by stud It to the other pole ot the battery or batteries, thus completing th`e circuit and working the motor. When a series of magnets are employed there will be one or more magnets pulling upon the ratcbetg wheel through the agency ot' armatures and levers at the same time. Itis obvious that by putting one or more distinct currents of electricity in circuit the power ot' the motor would be increased in the ratio ot' the number of elements or currents used, so that a governor could be arranged to regulate the power and speed and the different positions of the sliding` piece O, thus regulating the force of current to the resistance.

lt is not necessary to use a ratchet-wheel D, as any of the well-known friction devices muy be substituted therefor, the paw] L being so arranged that it binds in one direction of movement ot1 the armature S, but is free when moving in the other direction. i

Having now described my invention, wha I claim as new, and desireto secure by Letters Iatent, is

1. In an electro-magnetic motor, the ratchet- Vwheel D, or its equivalent, and commutator E,

in connection with one pole ot' the battery or current-generator, in combination with brushes M, two or more electro-magnets, I I, arranged around the ratchet-wheel, levers J, carrying armatures S, and pawls L, and rod K, by which said levers are caused to move in opposite directions at the same time, said magnets I I' being in circuit with the brushes and theother pole ot' the battery, substantially as and for the purpose specified.
